When you execute

PHP

echo "<script type='text/javascript'>alert(<?php echo $error; ??>);</script>";

you are already "in" PHP, so you don't need another (nested) enter/exit.
However, you will need to provide quotes around the string argument to alert(), because that's a javascript function executed in the browser, not PHP on the server.
Try this instead:

PHP

echo "<script type='text/javascript'>alert(\"$error\");</script>";
